that was my first thought. Shimano is very quick to tell you your chainline sucks. that was the main reason I liked di2: crisp Shimano shifting, but you didn't have to adjust the FD indexing when you were cross-chained. I did enjoy it but it wasn't mind-blowing for me. mechanical shifting is pretty excellent these days. depends what your priorities are though; it's more set and forget, that's for sure. if you hate bike maintenance or aren't skilled with it, it's 100% the way to go.
